8 Claims. (til. 28-32) This invention relates to the beaming of yarnand, more particularly, to a method and apparatus for the continuousbeaming of textile yarn.

At present, certain steps in the manufacture of textile yarn are of asemi-continuous nature. For example, textile yarn is conventionally spunand wound on pirns. These pirns are then mounted on beaming creels fromwhich the ends of yarn-are wound onto beams'by means of a beamingmachine. The production rate of yarn is limited by such factors asrepairing broken ends, replenishing exhausted pirns on the creel,removing filled beams and replacing them with empty spools.

This invention has as an object the provision of a method and apparatusfor the continuous beaming of textile yarn. A further object is toprovide means which will permit full beams to be replaced with emptybeams without interrupting the continuous yarn movement. A still furtherobject is to prevent yarn tension from rising above a critical levelduring the continuous beaming operation.

In general, the objects of the present invention are accomplished byapplying a pair of adhesive tapes coincidentally and transversely ontoopposite faces of a Warp of yarn ends travelling from a source ofsupply, such as, for example, the extrusion device of a continuous yarnspinning machine toward beam windup; severing the ends folloing thetaped location to divide the warp into a leading portion, whoseindividual ends are held in fixed lateral relationship to one another bythe taping, and a following portion; completing windup of the leadingportion onto a first beam and beginning windup of the following portiononto a second beam without interruption in the warp movement from thesource of supply. This invention comprehends doing this by means ofapparatus comprising taping means in the form of a pair of rolls mountedwith the roll axes transversely disposed with respect to a continuouslymoving warp of yarn ends and movable into contact with opposite faces ofthe warp, each roll being adapted to carry an adhesive tape into contact'with the travelling warp; severing means including a knife mounted forreciprocation transverse to the warp and adapted :to separate it into aleading and following Warp; and windup means, including a plurality ofyarn receiving beams, a beam-carrying reel adapted to support the beamsin a plurality of beaming positions, and a blower adapted to directsevered yarn ends onto an empty beam.

Referring to Fig. 1, there is shown at the right continuous windupapparatus and at the left taping appar-atus. Looking first at the windupapparatus (see also Figs. '2 and 5), spaced supports 15, 16 are mountedon base 17. Journalled in split pillow-blocks 18, 19 is shaft 20 towhich is affixed reel 21. This reel provides rotatable support forbeaming spools 22, 23 and consists of spaced arms 24, 25, the armshaving rotatably supported in bearings at their extremitiesbeam-supporting chucks 26, 27, 28, 29. Chuck 26 is provided with hingedportion 30 (Fig. 2) which permits insertion and removal ofbeaming spoolshaft 31. In like manner chucks 27, 28, 29' are adapted to permitinsertion and removal of beaming spool shafts. Driven sprocket 34 iskeyed to shaft 35 of chuck 26 and is operatively connected to drivingsprocket 37 by drive chain 39. Sprocket 37 is keyed to the drive shaftof motor 41 which is mounted on arm 25. Similarly driven sprocket 33 iskeyed to the shaft of chuck 27 and connected by means of chain 38 todriving sprocket 36, which is in turn keyed to the drive shaft of motor40. Motor 40 is mounted on arm 23:5.

Referring now to Figs. 2 and 3, motor 42, supported by bracket 43provides means for rotating reel 21, and acts through speed-reducer 44,keyed pinion 45 and bull gear 46, which is afiixed to shaft 20. Aretractable indexing pin 47 is mouned on support 16 perpendicular to theplane surface of bull gear 46. Solenoid 48 is arranged in relation topin 47, so as to exert force upon the pin opposite to that exerted bybiasing spring 49, which is positioned coaxially with the pin. Bull gear46 is provided with registration holes 47 for alignment with pin 47.

The integral shaft portions of chucks 28, 29 are centrally bored andthreaded so as to accept threaded push bolts 50, 51 on which arejournalled locking-clamps 52, 53. Rotatable collar 54 is journalled onshaft 20 between fixed flanges 8, 9. Integral with collar 54 isbeam-adjusting gage 55.

As shown in Figs. 1 and 4, presser-roll 56 and reciprocable knife 57 aredisposed in operating relationship with the above described beamingmachine by means of carriage 58. The carriage is supported by acombination of elements which includes vertical hollow posts 59, 60 (seeFig. 5), the posts being supported by base 17. The posts pass throughvertical bores in supporting-knees 61, 62 of carriage 58 thereby servingas guides for the carriage. A cross brace 63 extends horizontallybetween knees 61, 62 and is integral therewith. Roller-chain 64 isaifixed to carriage 58 by pad 66. The chain is trained oversprocket-wheel 67, under roller 68, over roller 70, aroundsprocket-wheel 69 and afiixed to cross-bar 71 of piston-rod 72. In likemanner roller chain 65 connects knee 61 and cross-bar 71. Air-cylinder73 is mounted on base 17 and provides support for piston-rod 72.

Referring to Fig. 6, presser-roll 56 is rotatably supthewarp-severported between knees 61, 62 of carriage 58 by means ofPatented Dec. 20, 1960 3 brackets 74, 75, bearings 76, 77 and shaft 78,whose axis is parallel to those of reel 21 and beaming spools 22, 23(see Fig. As best shown in Fig. 4, reciprocable knife 57 is mounted atthe free end of arm 79, pivotally supported by rod 80. Piston-rod 81 isconnected to arm 79 by means of rod 82 and contained with its integralpiston within double-acting air cylinder 83. Cylinder 83 is mounted oncross brace 63. Air-supply valve 84 and micro-switch 85 are mounted onthe horizontal shelf portion 86 of supporting-knee 62. Lever arm 87 ispivotally mounted on rod 80. A carriage hold-down catch is supported bybracket 11 and pivoted on rod 12, the force of biasing spring 13 beingopposed by that of solenoid 14a.

Synchronous motor 88 (see Figs. 1, 4, 5, 6) provides the driving meansfor presser-roll 56 acting through a series of transmission elementsconsisting mainly of sprocket 89, chain 90, sprocket 91, shaft 92,pinion 93, gear 94 and shaft 78.

Motor 95 (see Figs. 10, 11) provides the driving means for reciprocableknife 57, acting through cam 96, coupling rod 97 and bracket 98. Blower99 is mounted on arm 79 (see Fig. 4) and supplied with fluid throughconnector 100.

Looking now at the taping component of Fig. 1, (see also Figs. 7, 8, 9,12), vertical support 106 is mounted rigidly on base member 107. Plate108 is provided with guide elements 109, 110, which serve as guides formovable roll-supporting brackets 111, 112. Roll 113 (see Figs. 7 and 8)is supported in bearings 114 and 115 of bracket 112 by means of shaft116. This shaft is provided with a radially and axially bored passageway117. The cylindrical surface of roll 113 is provided with a series ofopenings 118. Otherwise the roll is fluid tight.

Roll 121 is similarly supported in bearings 122 and 123 of bracket 111,and is provided with a like series of openings in its cylindricalsurface. Shaft 124 is constructed with a bored passageway similar topassageway 117. Roll-supporting brackets 111, 112 are inter-connected bymeans of a chain and sprocket drive comprising chains 125, 125', uppersprocket-gear 126 and lower sprocket-gear 127, both sprocket-gears beingmounted for rotation on support 106. Chain 125 is trained aroundsprocket 126 and its extremities anchored to brackets 111, 112. Chain125' functions similarly, being trained around sprocket 127. Roll-shafts116, 124 extend through openings in support 106 and terminate inrevolving vacuum joints 130, 131. Pinions 132, 133 are keyed to shafts116, 124 and located within the body of support 106. Helical gear 134 isarranged vertically within the body of support 106 and supported inbearings 135, 136. This gear constitutes the driving element for pinions132, 133. Keyed to the upper end of shaft 137 of spiral gear 134 isbevel gear 138.

Shaft 139 is arranged normal to the axis of shaft 137 and is supportedin bearings 140, 141. Keyed to shaft 139 are bevel gear 142 and sprocketpinion 143. Bevel gears 142 and 138 form a co-operating pair. Coupling144 divides shaft 139 into a driven portion and a driving portion, thedriving portion constituting the drive shaft of synchronous motor 145.

Gear reduction unit 146 is mounted on support 106 and comprises the unititself, input shaft 147 and output shaft 148. Keyed to shaft 147 issprocket gear 149. Barrel cam 150 is keyed to output shaft 148 and iscontained wholly within the body of support 106. Chain 151 is trainedaround sprocket pinion 143 and sprocket gear 149. Cam-follower 152 issocketed in cam-pressure-relief-bar 153. Bar 153 is pivotally mounted onlug 154 and supported by compression spring 155. Threaded stud 156interconnects bracket 112, spring 155 and cam-pressure-relief-bar 153,adjustment being maintained by lock-nuts 128, 129. Adjustable stop 165is threaded into the internally threaded projection 166. Limit switch167 is mounted on support 106.

Also mounted on support 106 are warp-feed-rolls 157, 158 (see Fig. l).Synchronous motor 159 constitutes driving means for these rolls.Reference character 160 represents a warp comb, the principal elementthereof being reed 161. A warp-counter-roll 162 is rotatably supportedby bracket 163 and is driven by synchronous motor 164.

Now describing the operation of the above apparatus, as shown in Fig. 1,warp 14, proceeding from a continuous source of supply, passes overfeed-roll 157, under feed-roll 158, obliquely downward and through theteeth of reed 161, between the cylindrical surfaces of counter-rotatingrolls 113, 121, under counter-roll 162, obliquely upward and between thecounter-rotating surfaces of presser-roll 56 and the core of beamingspool 22 to windup on rotating beam 23. The warp is severed byreciprocable knife 57 when beam 23 has reached its full warp load.Rotation of this beam is stopped by suitable braking. The hinged portion30 (shown in Fig. 2) of chuck 26 and the corresponding hinged portion ofchuck 28 are swung open and beam 23 removed. An empty beam is now placedinto the position of beam 23, proper adjustment being obtained by meansof beam adjusting gage 55.

Simultaneous with the above severance of the warp, a new winding iscommenced on empty beam 22.

In effecting this, blower 99 directs a fluid, such as air or a waterspray, against the severed yarn ends thereby forcing them against therotating core of beam 22, which has been accelerated to a linear speedequal to that of the moving warp where the ends adhere sulficiently soas to start a proper winding without interruption in the continuous yarnmovement to windup.

As the windup of beam 22 proceeds, a level warp winding is maintained inthe following manner. Injection of air into cylinder 73 forcespiston-rod 72 out of the cylinder thereby exerting an upward force oncarriage 58, which in turn supports presser-roll 56 in contact with thewarp winding on beam 22.

The increasing winding on beam 22 forces presserroll 56 and the integralcarriage 58 vertically downward. When the windup of beam 22 has nearedcompletion, preset counter roll 162 automatically energizes motor 42,thereby bringing about a counter-clockwise rotation of reel 21. Thisrotation continues until beams 22, 23 have interchanged their relativepositions. The proper positioning of reel 21 is accomplished by means ofsolenoid-actuated indexing pin 47 and positioning holes 47 in thesurface of bull gear 46. As the full beam is moved from the positionoccupied by beam 22, presserroll 56 and carriage 58 are moved furtherdownward until the carriage is engaged by hold-down-catch 10 (as shownby the phantom position of Fig. 4).

Motor of the tape applying device is now energized, thereby acceleratingrolls 113, 121 to the speed of the travelling warp. Concurrent with theacceleration of rolls 113, 121, gear reduction unit 146 effects therotation of barrel cam 150, thereby causing follower 152 to forcebracket 112 downward. This movement of bracket 112 causes rolls 113,121, which have been manually loaded with adhesive tapes, to approachthe travelling warp sheet and apply the tapes coincidentally to oppositefaces of the warp, in this manner securing the individual yarn ends intheir parallel and coplanar relationships. The rolls are loaded with thetapes between dofling periods and are held in contact with the rollsurfaces by the partial vacuum created by placing the tapes over theopenings in the rolls. Proper alignment of the tapes during the loadingoperation insures that they will be adhered to the warp coincidentallyand the tapes will be in opposed relationship. Motor 145 is stopped uponthe return of bracket 112 by means of limit switch 167. Solenoid 14a isnow automatically; actuated, thereby releasing catch 10 and allowingpresser-roll .56 to return to a position of contactwith the travellingwarp as it passes partially around the new empty spool of beam 22. Asthe presser-roll 56 approaches this position, double-acting air cylinder83 is automatically actuated causing reciprocable knife 57 to be swungtoward the moving warp sheet. As knife 57 moves toward the warp, leverarm 87, pivoting on rod 80, closes microswitch 85, thereby actuatingreciprocable knife 57 and opens air valve 84 so that the fluid is forcedfrom blower 99. Following the severance, double-acting air cylinder 83is operated so as to withdraw knife 57 to an inactive position. Thiscompletes one cycle of operation, which cycle is repeated as the windupof each beam nears completion. The individual components which comprisethe apparatus of this invention may be actuated by suitable automaticcontrols.

In order to prevent interruption of the continuous beaming process ofthis invention, provision is made for preventing individual yarn tensionfrom rising above a critical level. This is done by synchronizing thesurface speed of those elements of the apparatus of the invention whichcontact the warp with the linear speed of the yarn as it is produced. Ina prefered embodiment of the invention motors 159, 145, 164 and 88 areof the A.C. synchronous type and are supplied with motive power from acommon A.C. electric generator, the generator being driven from anoutput shaft of the motor which drives the continuous source of yarnsupply. In this man ner the surface speed of the following warpcontacting elements is related to the linear rate of warp production:feed-rolls 157, 158; rolls 113, 121; counter-roll 162 and presser-roll56. In this same preferred embodiment, motors 40 and 41 are of the DC.variable speed drive type and their speed can therefore be controlledaccording to the torque created by the level of yarn winding on beams 22and 23. Such control may be achieved by means of equipment sold by theWestinghouse Electric Corporation under the trade-name Rototrol.
